Before Checksum, Söderberg & Partners had unit tests and a long written manual test plan that someone ran by hand before every release. The process was painful enough that releases became rare, which only made each one riskier. The pain compounded until manual testing couldn't be put off any longer. The team needed automated E2E coverage that could keep pace with how fast they were shipping with AI-assisted development, not slow them down further.

About
Söderberg & Partners
Söderberg & Partners is a Swedish financial services firm offering wealth advice and pension planning. Robert Gergeo's team builds the advisory assistant platform their advisers use to record client meetings and auto-generate compliance documents using AI. Advisers have stopped taking manual notes and now rely on the platform during live client conversations, so when it fails they're left rebuilding compliance records from memory. Quality isn't a nice-to-have, it's the foundation the entire workflow rests on.
the problem
Manual end-to-end testing was gating every release
the Solution
A persistent suite that grows with the product
Checksum uses AI to generate end-to-end tests from real application flows and maintain them as the product evolves. Instead of writing test scripts step by step, the team got a persistent suite that grows with the product and runs automatically before every release.
Persistent, not throwaway
Checksum builds a durable test suite that lives in your codebase and evolves with your product, instead of one-off scripts that have to be re-run or rewritten constantly.
Easy test creation
New flows can be added to the suite without manually writing out each step, so coverage expands as fast as the product does.
Continuous by design
Checksum runs on every release, catching regressions before they ship without anyone having to remember to kick off a test pass.
the Results
Trusted releases, reclaimed engineering time, and an AI platform their advisers can rely on
Full E2E coverage in weeks. Söderberg & Partners went from zero to full coverage within weeks, without having to build or maintain the test infrastructure themselves. That freed up time for more important work and let them ship faster.
More frequent, less painful releases
Releases used to be rare events because manual testing made them costly. With Checksum gating the pipeline, the team ships more often, with fewer bugs in production and up to 90 hours of manual testing reclaimed every month.
Confidence in every release
Since rolling Checksum out, the team has had one small production bug, and it was new functionality not yet covered by the suite. Beyond that, Checksum hasn't missed an issue. "We trust the releases now," Robert said.
A safety net for AI-velocity engineering
Robert's team embraced AI coding tools and started shipping noticeably faster. Higher velocity meant more features and more raw bugs, but a lower bug-per-feature rate because Checksum was catching regressions the team would have otherwise missed.
Manual testing made releases painful, so we couldn't deploy as often as we wanted. With Checksum, we have full coverage, we trust the releases, and we can focus on more important stuff than writing boring tests.
